I recently needed to consider the state of a System Architecture and consider the changes likely to be needed over time. Thus, I was trying to produce a “Roadmap” for the architecture into the future. The challenge was that the future is uncertain. Some items can be planned for, and others are dependent on the way the business and technological environments develop. These developments can be considered to be the product of various “forces” playing out in the environment of the system. How then can you address this complexity?

When requested to do so they would provide expertise to the delivery projects in the appropriate use of capacity management techniques, but they were primarily a gate keeping and monitoring function.
